GUARD FINGER FORYMOWING IVIIACI-ILIZITES4.

Application filed December 15 1926. ScrialNo. 154,965.

Our invention relates toimprovements in guard fingers for mowingmachines, and it consists in the combinations; constructions andarrangements herein described and claimed. V I I I An object of theinvention is to obviate slipping, turning and like accidental relativemovements of a guard finger relatively to its supporting bar withconsequent likelim hood of breakage of blades or sections of anassociated cutter or the cutter actuating pitman rod. I

A morespecific object'of the invention is the provision of-a guardfinger which has 15 means for contacting with [its supporting bar andwith adjacent guard fingers so as to prevent play or slipping of theguard finger on its supporting bar. I

A further object of the invention is the provision of a guard fingerhaving a portion adapted to protect the lower end of the securing meansbetween the guard finger and its supporting bar.

Other objects and advantagesof the inrention will be apparent from thefollowing description, considered in conjunction with the accompanyingdrawings, inwhich' Figure 1 is a'perspective view of a guard fingerembodying the invention and showing it in cooperative relation with afragmentary portion of an adjacent guard finger also shown, and thesupporting finger bar therefor, the latter being shown in dot andidashlines, I

Figure 2 is a side elevation of the guard finger with the finger'barshown in transverse vertical section, and Figure 3 is asectionsubstantially along the line 33 of Figure 2, I i I r A guardfinger embodying the invention has a forwardly tapering forward endportion 1, an intermediate portion 2 and an attaching rear 'end portion3. end portion 1 is ofgenerally conventional form and is provided with atransverseslot 4 in the upper part of its rearward portion.

The upper face of the intermediate port-ion 2 terminates at asubstantial distance below the bottom wall of the slot 1 and also belowthe upper edge ofa transverse flange 5 on the upper side of theattaching portion 3 at theffront end of'the latter, thus defining,

l The forward juncture with the intermediate portion 2 so that the frontwall 6 of the aforesaid trans verse channel will be of relatively greatarea. 1

The rear or attaching end portion?) of the 'mediate portion 2 of theguard finger may oppositelyextending lateral-lugs 9 at its guard fingeris wider than any other. portion of the guard finger and hasparallelside edges as indicated at 10 andafiat horizontal upper-face 11 which islocated below the plane of the upper edge of the aforesaid flange 5,thus producing a rearwardly facing vertical shoulder at 12.;Theattaching portion 3 0i the'guard finger is provided at itsapproximate center with a vertical aperture 13. The lower face of theapertured part of the at taching portion 3 of the guard finger is lo-vcated above thelevel of the wall face of the 7 From the foregoingdescription of the various parts ofthe device, the operation thereof maybe readily understood. The

transverse channel above the inner portion I of the tapering portion 1is adapted for the reception of the usual ledger plates (not shown)while the channel above the intermediate portion 2 is adapted to receivean overlying movable cutter bar (also not shown) from which the cutterblades carried thereby extend-into the slot 4. The; opposed faces of theshoulders 6 and 7 also will efiec-' tively guide the movable cutter barduring its operative movements. The rear end portion 3 of the guardfinger is secured by suitable fastening means, such as the bolt and nutindicated at 15 to a finger bar 16 which extends across the fiat upperface 11 of the rear end portion of the guard fingerand has its forwardedge disposed against the shoulder 12. It will be understood that aplurality I of the guard fingers are secured to the same.- finger bar sothat the side edges 10 of the adjacent guard fingers will .be adjacentto if not actually in contact with each other and the guard fingers thuswill be prevented from swinging about the axes of their securing means15 relativelyto the finger bar.

The lower end portion of the securing means 15 will be disposed directlyat the rear of the shoulder 14 and thus will be protected by the portionof the guard finger at the front thereof against the impact of a blowfrom any adjacent object or against accidental injury.

Obvious, our invention is susceptible of embodiment in forms other thanthat which is illustrated in the accompanying drawings, and we thereforeconsider as our own all such modifications and adaptations thereof asfairly fall within the scope of the appended claim. i

We claim As a new article of manufacture, a guard linger for mowingmachines comprising a forward end portion, an intermediate portion, andan attaching rear end portion, said forward end portion being slottedlongitudinally in a forward direction from its rearward end for part ofits length and having a pair of oppositely extending lateral lugs at itsrearward end, said intermediate portion having its upper faceterminating below the level of the bottom of the slot in the forward endportion, and the top edge of'a rear side wall extending parallel to thesaid laterally ate portion, sail rear end portion being aperl tured forthe reception of a fastening eleinentand having a transversely extendingearwardly facing shoulder at the forward edge of its lower side anddepending for a distance sufiicient to shield and protect the lower endportion of a fastening element positioned in thesaid aperture thetransverse width of the rear end portion being slightly greater thanthat of the rear end of the forward end portion of the guard in theplane of the laterally extending lugs thereof, the

intermediate portion being of a less width than the rear attachingportion and substantially equal to thatof the rear end portion of thetapered forward endportion and im inediately forward of the lugs.
